"Just like protesters who have taken to the streets and airports -- for the Women's March and against the travel ban -- scientists are planning their own march.

The group behind the March for Science in Washington just announced in a tweet that they will rally on April 22 -- Earth Day.

The march, born on social media -- through an idea floated in a Reddit thread and then followed up with organizing on Twitter, Facebook, and a Google form -- has gained a following of hundreds of thousands online."
